This nice treck close to Yulong Mountain (5600m high) is a must to see the variety of plants and stones available in the Natural Park. You will be walking in a valley formed by a glacier some time ago.
If you are lucky you will meet Yi shepherds gathering there herd. When you come in spring you can see dozens of the azaleas and rhodhodendron blooming.
